Bianchi bikes are steeped in tradition, yet continue to evolve in a sport where the width of a tire matters just as much as aerodynamic advantages when it comes to speed. That's part of why we choose Bianchi more often than not when it comes down to it. The Oltre XR4 Disc Road Bike Frameset represents road racing at its finest, and it's a go-to frame choice for pro teams for most races. With a fast ride and responsiveness, this bike encourages us to challenge ourselves with every sprint and climb. Oversized tubes, a press-fit bottom bracket, and a high-modulus carbon fiber layup are paired with Bianchi's patented Countervail technology to quell high-frequency road vibrations. This counters the bike's stiff efficiency. It's as perfectly at home on grueling mountain passes as it is crushing the flats. The Oltre inspires us to ride aggressively and put down serious speed. And, because of the Countervail technology we previously mentioned, it has the comfort for hours-long stages along with weeks-long tours. *Due to unprecedented demand in the global supply chain and the bike industry over the last 18 months, material weight and exact components are subject to change. We are working diligently to keep tech specs updated, and any adjustments will be minor. If you have any questions, reach out to a Gearhead by chatting online or calling 1-888-276-7130.
